WILLIAM H. SPENCE AND VIVA E. SPENCE, OF UNDERWOOD, INDIANA.

SCISSORS.

Specification of Letters Patent.

Application filed May 19, 1911.

Patented Apr. 30, 1912.

Serial No. 628,344.

To all whom it may concern:

Be it known that we, WILLIAM H. SPENCE and VIVA E. SPENCE, citizens ofthe United States, and residents of Underwood, in the county of Clarkand State of Indiana, have invented certain new and useful Improvementsin Scissors, of which the following is a specification, reference beinghad to the accompanying drawings.

This invention has relation to certain new and useful improvements inshears and scissors; and the object of our invention is to provide ameans whereby the blades are tensionally held together, insuring thecutting edges contacting at the cutting point at all times during theoperation of the shears.

Another object is to provide a pair of shears or scissors with a springcarried by the shears pivot, which not only yieldingly holds the bladestogether, but provides an auxiliary blade that can be used to rip a seamor cut a buttonholeQ With these and other objects in view the presentinvention consists in the combination and arrangement of parts as willbe hereinafter more fully described and finally pointed out in theappended claims, it being further understood that changes in thespecific structure shown and described may be made within the scope ofthe claims, without departing from the spirit of the invention.

In the accompanying drawings forming a part of this specification, andin which like numerals of reference indicate similar parts in theseveral views: Figure 1, shows a face view of a pair of shearsconstructed according to our invention disclosing the auxiliary knife inits ripping position. Fig. 2, shows a transverse sectional viewdisclosing the position of the outstanding flange as held against theedge of the connected blade, and Fig. 3, shows an enlarged detacheddetail of the auxiliary knife.

In our present invention we provide a pair of shears or scissors with asimply constructed knife having a spring end carried upon the pivotconnecting the scissor blades in a manner insuring the cutting edges ofthe blades being properly held together during the cutting operation,while the knife can be set at right angles to the shear blades, thescissors then serving as handles by means of which the knife may bewielded for ripping purposes or in cutting buttonholes.

As usually constructed the blades of shears and scissors after havingbeen used a considerable time wear loose, so that the cutting edges donot properly meet. In our invention the wear of the blades is taken upby means of a spring pressed nut, the spring employed serving a doublefunction.

In the accompanying drawings the numeral 1, designates the memberprovided with the fin r loop, and 2, the member provided with the thumbloop. These two blade members are conventional in size, shape andmaterial, each being providedv at a proper point with a pivot openingarranged to revolubly receive a pivot 3, which in the present instanceis in the form of a bolt, as disclosed in Fig. 2. This bolt 3, carries amilled nut 4.

Pivotally held upon the pivot forming bolt 3, is an auxiliary knife 5,preferably made of tool steel, which has a fiat under surface, as shownin Fig. 3, from which is continued the tang 9, the tang and blade beingconnected by the recurved blade portion 7 as clearly disclosed in Fig.2. This recurved portion 7 extends outward of the bottom face of theblade 5, and serves as a stop flange, being so located that when theknife 5, is carried at right angles to the blade 2, upon which the knifeis pivotally held, the outstanding flange 7, will ride snug against thesharp edge of the scissors near the pivot portion to hold the knife inproper position. As disclosed, the tang 9, extends parallel to the baseof the blade portion 5, both the blade and tang being traversed by abolt opening arranged to snugly receive the bolt 3. The outstandingflange portion 7, is provided with an integral ear 8, shown in Fig. 3,which is arranged for co-action with a socket 10, as clearly disclosedin Fig. 1, so that when said auxiliary blade 5, is out of workingposition the same will be snugly held to its carrying blade 2, the bladein this position being held against any casual or accidentaldisplacement. In Fig. 1, the position of the blade 5, when foldedagainst the shear blade out of working position, is indicated in dottedlines. The tang 9, serves as a spring to normally hold the blades 1 and2, yieldingly together so that the cutting edges of the blades will atall times meet at the cutting point, insuring a clear, sharp, cuttingaction. It is of course understood that the tension of the spring can beadjusted by means of the nut 4. lVhen it is desired to use the auxiliaryblade 5, for ripping or cutting purposes, it is simply necessary toslightly loosen the milled nut 4t, carrying the blade at right angles,then readjust the nut to insure the blade being securely held in properposition. It is of course understood that these auxiliary blades can bemade of various lengths.

A device constructed according to our invention is simple, inexpensive,and both durable and eiiicient in operation, and the adjustment of theauxiliary blade 5, into or out of working position may be effected withease, accuracy and despatch.

Having thus described our said inven tion, what we claim as new anddesire to secure by United States Letters Patent is:

1. In combination, a pair of shear blades each having a pivot opening, abolt within said openings to pivotally connect said blades, a knifeblade having its tang recurved and held parallel to the blade therecurved portion of the blade extending outward of the bottom face ofits blade to serve as a stop flange, said blade and tang havingregistering openings engaged by said bolt, the bottom face of said bladeworking upon one of said shear blades, and a nut threaded upon said boltto yieldingly clasp said shear and knife blades and tang, as and in themanner set forth.

2. In combination, a pair of shear blades each having a pivot opening, abolt within said openings to pivotally connect said blades, a knifeblade having its tang recur-ved and held parallel to the blade therecurved portion of the blade extending outward of the bottom facethereof to serve as a stop flange which has a part stamped out to forman ear, said blade and tang having registering openings engaged by saidbolt, the bottom face of said blade working upon one of said shearblades, a nut threaded upon said bolt to yieldingly clasp said shear andknife blades and tang, the shear blade carrying said knife blade havinga socket engaged at times by said ear, said outstanding flange arrangedto lie against the edge of the adjacent blade when said knife blade isat right angles to the shear blade.

In testimony whereof we afliX our signatures, in presence of twowitnesses.
